UPDATE of AVIAN INFLUENZA (H5N1) INFECTION in ADULT PATIENTS

A great narrative review πŸ’―πŸ‘
Thanks to @DavidJoffe64

2) Avian influenza, or "bird flu," is a major public health concern worldwide. The H5N1 strain is particularly dangerous, with high rates of transmission and death. While it mainly infects birds, this virus can also spread to humans, leading to severe illness.
3) Diagnosing avian flu requires specialized testing of respiratory samples. Early treatment with antiviral medications like oseltamivir is essential to manage the infection. Preventing exposure by avoiding contact with infected birds and animals is a key prevention strategy. Image
4) Researchers are working on developing effective vaccines to protect people at high risk. Pharmacists play a crucial role in this process, from medication management to patient education and vaccine administration.
5) Their expertise gained during the COVID-19 pandemic will be invaluable in addressing a potential avian flu outbreak.

Thanks for reading πŸ™

COVID-19 patients show altered immune responses and neuropsychiatric symptoms. SEVERITY CORRELATES with GUT MICROBIOME changes, systemic inflammation, and mental health issues.

medrxiv.org/content/10.110…Image
2) The study examined the connections between gut bacteria, immune responses, and physical/mental health symptoms in hospitalized COVID-19 patients. It found that many patients experienced significant physical problems, as well as high levels of anxiety, depression, and stress. Image
3) Interestingly, the severity of COVID-19 was linked to changes in the gut microbiome. Patients with more severe illness had lower diversity and richness of gut bacteria. Certain gut bacteria, like Mitsuokella jalaludinii, were associated with more physical symptoms, stress ... Image

Why Post-COVID recovery seems faster after an infection with the SARS-CoV-2 Omicron variant ?

This study looked at factors affecting recovery from long-term COVID-19 symptoms, called post-COVID-19 condition (PCC).
link.springer.com/article/10.100…Image
2) In this study, they used data from a large German study.

Key findings:
- Recovery was faster for people infected with Omicron or Delta variants compared to earlier strains. Image
3) - Once they accounted for the virus variant, vaccination status before infection did not independently affect recovery.
- Only about 37% of people with PCC had recovered within a year after infection.

SARS-COV-2 POPULATION IMMUNITY: EPITOPES, EPITOPES and EPITOPES !

An epitope is a small part of a molecule (like a protein) that the immune system recognizes and binds to, triggering a response.
journals.plos.org/plospathogens/…Image
2) This study examined how the antibody response targets different parts of the SARS-CoV-2 spike protein, depending on a person's prior infection and vaccination history. The researchers created a panel of mutant spike proteins to map the key epitopes ... Image
3) ...recognized by neutralizing antibodies. They found that primary infections with different variants elicited distinct antibody targeting patterns, highlighting the antigenic diversity between variants. Image

Time is of the essence: effectiveness of dairy farm control of H5N1 is limited by fast spread

Weekly bulk milk testing for H5N1 is often too late; better surveillance and focus on biosecurity are needed for effective intervention.

The "DOUBLE INSULT" of SARS-CoV-2 INFECTION:
Acute Illness and Reactivation of Latent Viruses Contribute to Long COVID

biorxiv.org/content/10.110…Image
2) The study examined over 1,000 hospitalized COVID-19 patients and found that many had reactivation of viruses they were already carrying, like Epstein-Barr virus and cytomegalovirus. Image
3) These reactivated viruses were linked to more severe COVID-19 symptoms and worse outcomes, including higher risk of death.

The researchers also saw that the reactivated viruses triggered specific immune responses, like increased inflammation and changes in gene activity. Image

AVIAN INFLUENZA A (H5N1, H5N6, H9N2 and H7N9) viruses in China

Diverse group of viruses, each influenced by its unique ecological and social factors, for example density of pig or human population emerged as common significant predictors for H5N1
frontiersin.org/journals/publi…Image
2) This study examined the patterns and risk factors for human infections with different strains of avian influenza viruses (H5N1, H5N6, H9N2, H7N9) in China from 2011-2024.

The researchers found that the geographic distribution of cases varied by virus type. Image
3) H5N1 and H5N6 infections were mostly concentrated in eastern and southwestern China, while H9N2 and H7N9 were more widely spread across the country. The timing of cases also differed - H5N1 showed seasonal patterns, while H5N6 and H9N2 had sporadic cases throughout the year. Image
